Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
Weight vs. Length for Red Drum (data from Jenkins 2004) The reference weight-length formula is used to calculate how much the individual fish would be expected to weigh based on its measured length. Then the condition index is the actual weight of the fish divided by its expected weight, times 100%.
The cobia (Rachycentron canadum) (/ ˈ k oʊ b i ə /, KOH-bee-ə) is a species of marine carangiform ray-finned fish, the only extant representative of the genus Rachycentron and the family Rachycentridae.

Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length [ edit ]
The rainbow runner (Elagatis bipinnulata), also known as the rainbow yellowtail, Spanish jack and Hawaiian salmon, is a common species of pelagic marine fish of the jack family, Carangidae. The species is widespread throughout the tropical and subtropical waters of the world, inhabiting both coastal and offshore areas.
Individual fishing quotas (IFQs), also known as "individual transferable quotas" (ITQs), are one kind of catch share, a means by which many governments regulate fishing.. The regulator sets a species-specific total allowable catch (TAC), typically by weight and for a given time per
Arctic grayling grow to a maximum recorded length of 76 cm (30 in) and a maximum recorded weight of 3.8 kg (8.4 lb). Of typical thymalline appearance, the Arctic grayling is distinguished from the similar European grayling ( T. thymallus ) by the absence of dorsal and anal spines and by the presence of a larger number of soft rays in these fins.
The International Game Fish Association (IGFA) all-tackle world record chain pickerel is a 4.25 kg (9.4 lb) fish, caught in Homerville, Georgia on February 17, 1961 by angler Baxley McQuaig, Jr., while the IGFA all-tackle length world record is 65 centimetres (26 in) long, caught in Henderson Harbor, Lake Ontario, New York on November 4, 2019 ...
